Verify that the EAPS 225 label says for EXAMPLE, EAP225(US) V3 or EAP225(EU) V3.

If you find such information, you must enter the tplink page where you find the support, in the Firmware section, you must find one exactly the same, you must search for all those that are from the country of manufacture of the product, for example (US) and also the version of the equipment, for example V1 or V2....

it is extremely important that you also verify that OMADA CONTROLER, previous versions or SDN versions, is fully compatible with the version of EAP 225 you are using.

When you download the OMADA Software version, verify that your EAP is in the supported list.

I think from experience you must have this problem.

Also verify that the POE Switch complies with passive or active poe (802.3 af / at)

Verify that the poe switch has the necessary power to keep on the consumption of the requirement of the sum of the 3 EAPS or any connected device.

for instance
EU: 10.5W
US: 12.6W

X3 EAPS = 40W minimum

Luck!
